DateAndFlags (I2P Anonymous Network - Java Documentation

java.lang.Object
- net.i2p.data.DataStructureImpl
- - net.i2p.data.DateAndFlags

All Implemented Interfaces:

Serializable, DataStructure

Direct Known Subclasses:

SendMessageOptions
```
public class DateAndFlags
extends DataStructureImpl
```
A six-byte Date and 2 bytes of flags, since a Date won't encroach on the top two bytes until the year 10889. The flag format is not specified here. The bits may be used in an application-specific manner. The application should be designed so that a flags value of 0 is the default, for compatibility with an 8-byte Date. See extending class net.i2p.client.SendMessageOptions for more info. If we really need some more bits we could use the first few bits of the third byte.

Since:

0.8.4

                      IOException
```
    Description copied from interface: DataStructure
    
    Load up the current object with data from the given stream. Data loaded this way must match the I2P data structure specification. Warning - many classes will throw IllegalStateException if data is already set.
    
    Parameters:
    
    in - stream to read from
    
    Throws:
    
    DataFormatException - if the data is improperly formatted
    
    IOException - if there was a problem reading the stream
  - writeBytes
```
public void writeBytes(OutputStream out)
                throws DataFormatException,
                       IOException
```
    Description copied from interface: DataStructure
    
    Write out the data structure to the stream, using the format defined in the I2P data structure specification.
    
    Parameters:
    
    out - stream to write to
    
    Throws:
    
    DataFormatException - if the data was incomplete or not yet ready to be written
    
    IOException - if there was a problem writing to the stream
  - toByteArray
```
public byte[] toByteArray()
```
    Overridden for efficiency.
    
    Specified by:
    
    toByteArray in interface DataStructure
    
    Overrides:
    
    toByteArray in class DataStructureImpl
    
    Returns:
    
    may be null if data is not set
  - fromByteArray
```
public void fromByteArray(byte[] data)
                   throws DataFormatException
